such license applies only to those patent claims licensable by such Contributor | ||
that are necessarily infringed by their Contribution(s) alone or by combination | ||
of their Contribution(s) with the Work to which such Contribution(s) was | ||
submitted. If You institute patent litigation against any entity (including a | ||
cross-claim or counterclaim in a lawsuit) alleging that the Work or a | ||
Contribution incorporated within the Work constitutes direct or contributory | ||
patent infringement, then any patent licenses granted to You under this License | ||
for that Work shall terminate as of the date such litigation is filed. | ||
|
||
#### 4. Redistribution | ||
|
||
You may reproduce and distribute copies of the Work or Derivative Works thereof | ||
in any medium, with or without modifications, and in Source or Object form, | ||

|
||
* **(a)** You must give any other recipients of the Work or Derivative Works a copy of | ||
this License; and | ||
* **(b)** You must cause any modified files to carry prominent notices stating that You | ||
changed the files; and | ||
* **(c)** You must retain, in the Source form of any Derivative Works that You distribute, | ||
all copyright, patent, trademark, and attribution notices from the Source form | ||
of the Work, excluding those notices that do not pertain to any part of the | ||
Derivative Works; and | ||
* **(d)** If the Work includes a “NOTICE” text file as part of its distribution, then any | ||
Derivative Works that You distribute must include a readable copy of the | ||
attribution notices contained within such NOTICE file, excluding those notices | ||
that do not pertain to any part of the Derivative Works, in at least one of the | ||
following places: within a NOTICE text file distributed as part of the | ||
Derivative Works; within the Source form or documentation, if provided along | ||
with the Derivative Works; or, within a display generated by the Derivative | ||
Works, if and wherever such third-party notices normally appear. The contents of | ||
the NOTICE file are for informational purposes only and do not modify the | ||
License. You may add Your own attribution notices within Derivative Works that | ||
You distribute, alongside or as an addendum to the NOTICE text from the Work, | ||
provided that such additional attribution notices cannot be construed as | ||
modifying the License. | ||
|
||
You may add Your own copyright statement to Your modifications and may provide | ||
additional or different license terms and conditions for use, reproduction, or | ||
distribution of Your modifications, or for any such Derivative Works as a whole, | ||
provided Your use, reproduction, and distribution of the Work otherwise complies | ||
with the conditions stated in this License. | ||

||
#### 5. Submission of Contributions | ||
|
||
Unless You explicitly state otherwise, any Contribution intentionally submitted | ||

conditions of this License, without any additional terms or conditions. | ||
Notwithstanding the above, nothing herein shall supersede or modify the terms of | ||
any separate license agreement you may have executed with Licensor regarding | ||
such Contributions. | ||
|
||
#### 6. Trademarks | ||

reproducing the content of the NOTICE file. | ||
|
||
#### 7. Disclaimer of Warranty | ||
|
||
Unless required by applicable law or agreed to in writing, Licensor provides the | ||
Work (and each Contributor provides its Contributions) on an “AS IS” BASIS, | ||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied, | ||
including, without limitation, any warranties or conditions of TITLE, | ||
NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You are | ||
solely responsible for determining the appropriateness of using or | ||
redistributing the Work and assume any risks associated with Your exercise of | ||
permissions under this License. | ||
|
||
#### 8. Limitation of Liability | ||
|
||
In no event and under no legal theory, whether in tort (including negligence), | ||
contract, or otherwise, unless required by applicable law (such as deliberate | ||
and grossly negligent acts) or agreed to in writing, shall any Contributor be | ||
liable to You for damages, including any direct, indirect, special, incidental, | ||
or consequential damages of any character arising as a result of this License or | ||
out of the use or inability to use the Work (including but not limited to | ||
damages for loss of goodwill, work stoppage, computer failure or malfunction, or | ||
any and all other commercial damages or losses), even if such Contributor has | ||
been advised of the possibility of such damages. | ||
|
||
#### 9. Accepting Warranty or Additional Liability | ||
|
||
While redistributing the Work or Derivative Works thereof, You may choose to | ||
offer, and charge a fee for, acceptance of support, warranty, indemnity, or | ||
other liability obligations and/or rights consistent with this License. However, | ||
in accepting such obligations, You may act only on Your own behalf and on Your | ||
sole responsibility, not on behalf of any other Contributor, and only if You | ||
agree to indemnify, defend, and hold each Contributor harmless for any liability | ||
incurred by, or claims asserted against, such Contributor by reason of your | ||
accepting any such warranty or additional liability. | ||

## AWS Region Certificates for Go | ||
|
||
Embeds region certificates from AWS (run `go generate ./...` to refresh them) - AFAIU they can only be downloaded as part of documentation. | ||
|
||
Can be used to validate EC2 [instance identity documents](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-identity-documents.html) using the `rsa`/`base64-encoded signature`. | ||
